I've got a couple of very small self tappers which have broken off flush

damage to the bodywork?

Carefully. ouch

Squirt with PlusGas and leave for a day, or a spot of diesel if you
have no PlusGas. Then I'd try the one of the JML Screw Removers that
Homebase are (were?) selling for £4.99/set. But being self tappers
they might be too hard for the remover to cut into to get a grip.
