This is what works for me. It might not for you. There are many different "right" styles and you'll have to find one that works best for you.
Head vertical and up. Look through the corner as far as you comfortably can. This will make the corner seem slower and proper head position, and looking where I wanted to be improved my riding 100%.
Get both cheeks off the seat. Carry your weight on the balls of your feet and use the inside of the high leg to locate yourself on the bike like an archer uses the corner of his eye to shoot consistently. DoNOT use it to carry any significant amount of weight. By doing this you'll be carrying your weight low on the bike and allowing it to move independently from you. This takes endurance and a lot of leg strength, but you'll be amazed at how much the bike will correct for bumps and pavement imperfections all by itself, if your body weight isn't restricting movement.
This kid has just about the best natural body position I've seen, close up.
Coming off the corner and moving into tuck on the front straight.
