I live on Lake Erie.
Walleye I use a nightcrawler harness, and attach it to a sinker about 2.5 feet above the harness. I troll the lake shore from 30-70ft depending on the year. 1.8mph keeping the bait about 5-10ft off the bottom usually. Just caught 5 last night in 50ft using that method.
Smallmouth is way to easy imo. Go to a creek and some crayfish, take the claws off them, and attach a hook through the tail and use a sinker. This is very important. FIND A ROCKY AREA!!! Smallmouth love rocks, rock bars, structure, expecially in lake erie because that is where the gobys hang around. Cast out and bounce that sinker and crawfish along the bottom and be ready for a good time.
If you need anymore help let me know, I have fished it my whole life. lol You will do much better by using a boat.
