If it's broken outside the head, use a grinding wheel to grind a slit in the bolt. Then grab it with a pair of vise grips and stick a flathead screwdriver in the slit. Use both to loosen the bolt out.
If it's broken inside the head, you're gonna have to either drill it out or drill a hole into the bolt to get an "easy out" in there. I would strongly recommend using a reverse drill bit in this situation. Sometime the bolt will come out with the force of the reverse bit. You need to be careful with an easy out though. They are strong but brittle. If you use too much force, it'll break and you'll find out then just how uneasy they can be.
When you get it out and get new bolts, most people would recommend using some kind of thread locker. I do not recommend any. I would raher a bolt back out then break off and have to fight it and the locker to get it out.
