Whew!!
There are so many ways to answer this there really isn't a starting point.
There are literally hundreds of threads on here that will answer your questions with a lot more depth and insight that I can give..
But, I'll at least start...
Not knowing what the water is like in your lake...clean. stained, deep, shallow, rocks, vegetation, pads, reeds, grass, docks etc.
Do you fish from a boat or do you walk the shore??
See what I mean?
If it were me and knowing that worms already work, I'd concentrate on those first. Try different sizes, shapes and colors.
There are thousands of choices.
Throw a T rig all over the place.
Drag, hop and swim it to see what they want on any given day in the type of water you're fishing. If you have thick vegetation peg the weight to the hook and try that switching to a small, sleek craw type bait with a lot of appendages.
Grab a spinner/chatterbait, a small sq bill crank bait, rig a drop shot in deep water, and of course don't leave without throwing a jig.
You asked an open ended question there Pal, I can't give you a definative answer because there isn't one.
Try them all over your next few outings and see what happens.
It really wont take long.
Good Luck and Welcome
Mike
