PUFFA is a mnemonic I've run into whilst flying here in Australia. Where I was trained to use GUMPS, the local folk here use PUFF (sometimes PUFFA):

Prop - If applicable, make sure the prop is at full fast (high RPM)
Undercarriage - If applicable, make sure gear is down
Flaps - Set flaps for landing as appropriate
Flaps - cowl flaps set to OPEN for go-around/recovery
(Autopilot - Make sure autopilot is OFF.)
