I need a very small low power level shifter to turn on a FET. This is infrequent on/off switch duty stuff so the gate current can be very low and it doesnt need to be very fast.
Thanks.

Power levels, or voltage levels?
If your subject line says it right, you need voltage level conversion. If so, try an n-channel JFET, gate to common ground, pull-up resistor on the drain to 12V, input to the source. Anything over 1 to 2V input should be fine. Without having seen your circuit I can't be sure, but this might all be doable with a single FET.
