Just run a 3 wire cable to the switch box from the existing light fixture. You do this because there is no neutral carried to the switch box and it really is all you need . .
then as said earlier a two wire cable from the light fixture to the fan. You will use the red wire in the 3 wire cable to switch the fan, the black to switch the light, white to get power to the switch box (mark it black on both ends) and bare for ground. The red will connect to the black of the two wire plus ground cable you ran to the fan. Make sure you maintain the same wire size as the power wires. The white wire (power) in the switch box will need two pigtails to get power to the two switches.
Wire nuts are all you need.
This is your alternate method. I have the fan and light reversed but you can see what is going on.
