First, realize that you will need to have a voltage supply at your output voltage (i.e. 3.3V or 5V).
If you want a simple, few component solution, harerod's solution of a NPN BJT is good (input through a resistor to the base, with a pull-up resistor on the output), but will invert your signal (unless you make it two-stage). Speed might be a bit slow, and it will have higher power consumption when the BJT is "on" due to the pull-up resistor on the output.
If you wouldn't mind using a few extra components (like voltage regulators), I'd suggest a dual-supply logic converter IC like TXU0104-Q1. ESD, input overvoltage, and output short protections could also be implemented. I'd likely power it from a "5V USB" source.
(BTW, your circuit probably won't work properly since there is nothing to pull the middle gate node down to 0V, so the 2nd MOSFET will never be turned off)
