My dad would tell you that "you're not holding your mouth right." But, me being a smart azz isn't going to help you. [

You've got some good advice, and some that doesn't really matter either way. (IMHO) I guess it really depends on what you want to catch, and how big you want them to be.
I've seen more than one recommendation to use tiny little hooks. If you care about releasing the fish after you catch them, I wouldn't necessarily agree with that. If you use a medium size hook, I like a #8, you've got a lot less chance of gut hooking the fish. I don't know how big the panfish get up your way, but down here in the carolinas, we target the big ones. (unless we're looking for catfish bait) The only advantage to using a tiney hook is that you can catch the little fish. If you use a larger hook, you're more than likey narrowing down to a more desirable size quarry.
Keep your rig simple. It's not rocket science. Panfish are very simple to catch. If you're not hooking the fish, it's because they are little. Move on. During this time of year, when it's blazing hot, you need to get IN the structure. Someone mentioned fishing on the bottom during the day, and in the upper water column during the early and late hours. That's good advice, and you should follow it. Also, if you can find a few spots on the lake that stay shady, and have structure, you can get them in the upper water column during the day there as well. If the water is deep, keep adjusting the depth of your bait. They may not be right on the bottom, rather, a few feet off of it. Their strike zone is going to be much smaller during the heat of the day. So, you'll really have to experiment with your depth and location until you find them.
Don't just throw your bait out and leave it either. Forget all the bull sheet you hear about bobber fishing. When it hits the water, give it a light twitch every now and then. Give the reel a couple cranks, then twitch it again. (don't reel your line into the structure though) Bream are attracted to movement, and you might trigger an impulse strike even if they are not hungry. Bream are stupid, so cator to that charractor flaw. Use shiney hooks, like those neon yellow looking ones.
Next, spool your reel with braid. You'll gain sensitivity and you'll be able to get out of snags a little better with out having to re-rig every few minutes. I like 10 pound power pro or Suffix. I'm actually becoming partial to Suffix based on it's performance offshore. (I primarily fish offshore along the SC coast) It's very strong, very castable, and I like the colors it comes in. I also noticed it doesn't fade like Power Pro does, atleast not as rapidly. But, don't think i'm bad mouthing Power Pro, because it's also an exceptional line. Make sure you know your knots if you're going to use braid though. If you use the wrong knot, or fail to tie it properly, you'll start loosing your terminal tackle.
Lastly, the least important aspect of panfishing is the bait. Anyone can tell you what they want, but remember I said that panfish are stupid. I've caught them on bare hooks, on bread balls, bacon, fatback, bloodworms, smoked sausage, and what the hell ever else you can think of. The exception to the rule would be Crappy, which are a prized catch, in my opinion. They are an excellent target species and have very tastey flesh. They are in my top three of favorite fresh water table fare. If I were to target panfish, there are two baits I wouldn't leave home with out though; that's wax worms and crickets. And if the caterpillars are out and about, there isn't a finer bait. Shake some off a tree and head out. The biggest of the fish will fight for live catapillars, rather they are hungry or not.
Don't be affraid to cast out in the open water either. I've caught some of my biggest panfish 15' off the bank, no where near a hole or structure. During the time of the year when the panfish are bedding, you can actually smell the fish when you get close. It's freaky, but effective. If you're walking along the bank, and smell fish, that's your spot. Give a few minutes, and more times than not, you'll snag a few.
lastly, if the fishing gets really tough, go buy a cast net.
