I guess it really depends on what you are fishing for and what time of year it is. I would recommend searching your lake on Google earth first. This will give you the general layout of the lake. From there, I would start looking for spawning areas ( usually shallow back bays )
after searching out those areas with some kind of horizontal bait like a spinnerbait , jerkbait or maybe a topwater.
Good green weeds are always a good starting point. If you start finding fish using these techniques, you can slow down and pick apart the area with something slower and more vertical like a jig.
Once you are done checking some of these areas. move out to the points outside of the bays. Start the search process over.
After you have exhausted these areas, then I would suggest moving out to the main lake and use you electronics to find any main lake shoals , islands ect. Repeat the same process
