I have found jigs and rubber tales to be effective for walleye. I use single and double tails, shad bodies, lizard/salamander bodies and crayfish bodies. The Storm swim shads in 3-4 inch range can be effective to.
Storm hot n' tots with there wild searching action also trigger alot of walleye bites, along with other fish species.
Try these lures in a natural forage color and a few in some hot color like firetiger.
With the fall upon us they should be a bit more aggressive, good luck.
