Be careful not to overheat any one area, you could scorch the paneling, or set the edge of the paper on fire. The knife will help get a corner started and then clear away the gummy residue. Afterward you'll have strip what's left of the gum, either with a household cleaner, or with a chemical agent.

An utility knife and a crowbar. Pry the paneling away from the wall and use the utility knife to cut the seams between pieces.
