With vise grips you may be able to get a good enough grip on what's left of the bolt to remove it. Locking wrench vise grips are best suited to give you maximum grip on a hex bolt. The second best vise grip for removing a nut or bolt are straight jaw vise grips.
If you have a propane torch you can apply heat to the bolt to help loosen it. Be careful using an open flame around an engine bay or any other location where there could be flammable material.
Use a hack saw, air cut off tool or a Dremel to cut a grove into the bolt head and then use a straight blade screw driver to remove it.
