Smallmouth?
If it's early and they are not on the beds yet, just about any streamer should work. That, and I've had GREAT luck with large Iso mayfly nymph imitations, sunk hard, them swam up in spurts, like they are getting ready to hatch. Time this with a real hatch, and HANG ON!
If they are on the beds, anything will work.
Poppers, frogs, and crawfish imitations are standards, and for really good reason.
