I'm sure there's some great books on smallmouth flies (stuff by bob clouser and harry murray come to mind) but it may be tough to find a lot of different stuff in one spot.
Before you spring for a book, here's a great resource for you to check out:
Fly Patterns - Warmwater Fly Tyer - by Ward Bean
If you click on the different categories (in red) it will take you to a list of patterns in each category, and you can click on the individual patterns for step by step instructions. If you have a bit of tying experience you should be able to follow them with no problem.
If you're new to tying, feel free to ask here if you have any questions about materials or tying techniques--
I'm sure you'll get a lot of specific suggestions for patterns from some of the smallmouth sharpies on this forum -- and we have a bunch of 'em.
Some "standards" for smallmouth include stuff like clouser minnows, gurglers, crayfish patterns, buggers (and variations like the chili pepper), leeches, stuff with spun deerhair (divers , muddlers, flash dancer) and rabbit strip stuff (zonkers etc) large nymphs and big dries like hoppers Stimulators and Wulffs (in warmer weather).
