Inverter constructed using LDMOS transistors
What you are looking for is a level translator circuit.

The core of this picture is what you will looking for.  There is no quiescent current.



This picture is snipped from EE-Times article here as it gives some good background.

I've implemented similar circuits lots of times.  It can be used to also shift the negative rail too, but the circuit is flipped and the transistors inverted (PMOS for NMOS etc.).  The catch is that you can only shift one rail at a time, i.e. first the bottom rail and then the top rail.  Having an output inverter is useful as this circuit is sensitive to loading on the internal nodes of T5 and T7.

You need to recognize the key aspect of the circuit can be reduced to the following:
