Wire gauge is determined by the required output current. Estimate the wire length from the core size and number of turns, the calculate the resistance. Remember that the resistance of copper is a function of temperature, so you can use the wire resistance at your expected transformer temperature. The wire resistance is in series with your output, and you can perform the R*I^2 calculation to determine the power you will be generating which will be both a transformer loss and a heat source for your design. Remember that you will be supplying pulsed current, so your voltage drop will be greatest immediately after switching off the primary, and the voltage must be high enough immediately after switching.
