I'd suggest investing in a hydrographic map of Strike. There is one available from the Fish-n-Map Co:

If you have an iPhone or Android smartphone, Navionics makes an app that has Strike, along with a ton of other lakes and reservoirs all over the US. It costs about $10:

I have the one for Android, and it's very useful. If your device has a GPS, it will show your location and direction right on the map.
Watch the temperatures for a few days before your trip. If the temps are above 60, the crappies and other warmwater fish will start moving into shallow areas to feed and put on weight for the spawn. Those areas warm up faster than the main body of water. I'd launch at Cottonwood or the Narrows and fish along the shore. Just look for any spot that's shallow, gets a lot of sun and is protected from the wind.
If the weather is colder, try fishing out in the narrows where the depth drops off. If it's not too windy, you can try fishing the humps out in the main body of the reservoir. It's a spot where the bottom comes up from about 80 feet to within 35 feet of the surface. There are two peaks, with 60 feet depths between them. It's easiest to find them on the map, but there are usually a few boats out there. It's not too far to reach from a float tube, but it is out in the main body of water. Watch out if the wind kicks up.
