how is this for a start?

Your right crossroads I mis-spoke by saying schematic. The parts are (from top to bottom, L to R) IR Receiver, MOSFET, power supply for motor, and motor/fan. There is also a resistor for the IR Receiver and a Diode for the MOSFET.

I want the fan to be on until turned off by another press of the remote.
