As mentioned above i too would use a large worm or even a lizard texas rigged working it slowly and bouncing it off bottom.
Another bait you might try is a jig and pig. I never throw a jig under 1/2 oz. Go with natural colors such as a dark brown/green/or black. Remember to work it slow and those lunkers will soon enough appear again!
P.S-make sure to watch ur line, oftenly when im using a jig, a bass will take it when its sitting or when i just bounced it and i wont realize it had biten.
