Of course, you have to find them first, otherwise advice on lures and rigs won't matter too much. As a generality, smallies will be found in somewhat cooler, deeper water than largemouth and are not as cover-oriented, although they do like rocks and rocky bottoms, as was stated above.
They will take a full variety of lures. Often you can use exposed hooks, like on jigheads, because they're not in heavy cover like largemouth. And you can usually use lighter line because of the open water they're often found in.
Good luck. You will find out why someone once said of them, "inch for inch and pound for pound, the gamest fish that swims."
