How do I catch jumping walleye in 4-12 feet of water?

Theres a lake i fish in northern michigan that is mostly dominated by walleye, and smallmouth b, The lake is relatively deep, close to 80 ft at the deepest, and i never have any luck during the day for walleye or small mouth. I've noticed that right around 9 ocklock p.m., the fish begin to move into shallower water, ranging from 4 ft to 12 ft, and they are jumping, just tons of fish jumping left and right, but im finding it increasingly difficult to hook into any of the fish. What can I do or use to entice fish to bite?
