2x3 input nand gates and 2 2 input nand gates.
search for J-K Flip-Flop. Both J and K inputs should be tied to positive, and the CLK to your switch.
I believe this could also be done using simple transistors, but I don't remember that far back.
Why would you want this though? an push button On-Off switch is much-much easier (and cheaper).
This variation of the JK Flip-Flop is called a T Flip-Flop (for Toggle).
I found a sample structure:
The structure is :
disregard the term "Clock edge" since that will just be the signal from the momentary switch going from GND to Positive then back to GND
