Some of it is just maintaining physical awareness of how you are walking (which it sounds like you're already somewhat doing).
But one actual tip I would give is to lead with your chest when you walk. Oh, and let your arms swing freely, with your hands facing your legs (not turned backwards) and try to place your feet down pointing directly forwards, not having one foot turned outwards, as I often see.
