Hi Dustin
I'm the lurking cheesehead of the site. The choice of flies you might use has a lot to do with your flyrod as well as the locations you fish. Not to mention your line, casting ability etc.
A good selection of flies to carry might be clouser minnows, wooly buggers, a few poppers in various colors, a crayfish imitation or two, and perhaps a few streamers.
To be honest smallies can be pretty darn agrressive at times and will take anything they can swallow including mice, frogs, crayfish (very important on their menu!) leeches, ducklings, and all manner of smaller fishes. At other times they can be "keyed in" to specific insects. Hellgramites, dragon fly nymphs, stone fly nymphs hexagenia limbata mayflies (the great big ones to about 2.5 inches) There are not many limitations to what they will take at any given time.
Look around the site here, there are several really great looking patterns that have been put together by these guys. I know that richmc does some incredible things with a bohemian yarn that just scream big fish!
Welcome to the maddening addiction of flyfishing smallmouth bass but be warned once you start catching smallies on a long rod there is no turning back.
Good luck,
Don
