I do the obvious stuff like keeping the tires inflated (usually to ~38 psi), gradual accelerations, and using cruise control or equivalent manually controlled constant speed when possible.

With the CVT, you have probably noticed that it often automatically changes the gear ratio to create engine compression breaking when you are coasting (it picks a lower gear and revs the engine). This is especially true when coasting down hill. This is an annoying feature and one that Subaru could have done without. I'd much rather decide when to do this myself with the paddles. So, if I am trying to coast to maintain momentum and save fuel and if the CVT auto shifts to a lower gear, I'll use the paddles to pop it back into a higher gear to minimize the compression breaking... thereby maximizing the ability to coast and save fuel. If I know I am going to be on a long steady descent, I'll often shift into manual mode and use the paddles to shift into the highest gear for this same benefit.
Actually you don't have to shift to manual (in mine anyway) I just hit the upshift and it goes to 6th and stays there until the engine braking is over.

Also, when approaching the bottom of a hill where I know the CVT will "downshift" to higher rpm than 5th, I just pull it into manual (6th if you do it before you hit the hill) and when it starts to slow paddle down to 5th and let it slow going up the hill. It's kind of intuitive, but the lower the gear the lower the mpg.
