Get a nice lake map and look for rocky offshore points and/or saddle areas where two points come together. A GPS is not a bad idea either.
What I have been doing is setting a tip-up in about 10 to 12 feet with a shiner. I then drill several holes going out to about 30 feet or so. Start jigging in the deeper holes and move shallower as the evening progresses. The tip-up will also let you know when the walleyes have moved up the break.
Jig with spoons tipped with a minnow head or I have also had good luck with a perch colored jigging rapala (about size W-5).
If you are catching/seeing perch while it is still light, you are in the right areas. Where there is food, there will be walleyes.
I have had pretty good luck on Pelican this year. Some pretty nice fish also.
Good luck.
