I use different methods than most people but basically, I taught my two by just having them on leash and gently pulling them back if they got too far and encouraging them to go faster if they lagged. Everyone in Kai's first set of obedience classes used treats to lure the dogs as well; that seemed to work alright. If your dog is food motivated, you should have no problems having him follow you. When I used treats, I found it much better to hold the treats directly in front of me right on my tummy, rather than beside me. When I held it beside me, Kai would often jump up and nip while walking.
