"Fired up" is one of those phrases that is hyphenated when it is used as a modifier preceding whatever it is modifying, but not hyphenated when it is used as a predicate adjective. For example, if you say "Everyone was fired up about the new project", "fired up" is a predicate adjective and not hyphenated. However, if you refer to someone's "fired-up speech", "fired-up" is a modifier that precedes "speech" and is therefore hyphenated. Using "fired up" as a predicate adjective is more common.
