If you have Maya 7, then you can render in Maya Vector, its in render settings along with MentalRay, Hardware and Software. It takes some getting used to on making it look good but you can get some cool stuff out of it with a little trial and error.

If you have Maya 6 or below, you can download something called NPR (non photorealistic render) here and it gives you the same look but all the colors are made in the hypershade.
