I've been largemouth bass fishing for a couple years so I'm trying to learn some tricks for more species especially smallmouth. What are the best lures and areas to fish for smallmouth 

There's a ton of info on here. Just scroll through and look, search various things, etc. There have been similar threads to yours recently so it shouldn't be too hard.

Welcome aboard! As said, there's a lot of information here to digest. Without knowing where you are fishing and what kind of lake, or reservoir, or river you are targeting, it's next to impossible to answer your questions.

Just a start, try rocky areas.. 

Find A Crawdad bed and thats a great area.

Well.................the #1 requirement is...........make sure there are smallmouth in the bodies of water your fishing. A lot of lakes/ponds/rivers/etc....have both, but a lot have just one or the other.
