Doyle's half-volley found the bottom corner inside the first minute after a long throw, before Josh Scowen came close with a header for Wycombe.
Garry Thompson hit the bar for Bradford before two late goals for the Bantams.
Will Atkinson found the net from James Hanson's pass and Doyle converted a penalty two minutes later.
