I find simply the best economy up a hill is getting as close as possible to whatever RPM + throttle opening offers the best efficiency, and of course you want to keep speed down so you not pushing too much air either. If your car does best FC at 60-70kph, then depending on the hill and your car speeds as low as 30kph might be ideal.

Staying in the 2000-2250rpm range around some of our steep hills and this seems to have dropped my FC on my commute.
Unfortunately, Boulcott Street is the hill I have been going up the most lately, and with 2 sets of roadworks in that tiny stretch, I'm almost always accelerating up it as well. I got 33MPG (7.1l/100km) on my last tank, so I must be getting something right, but I suspect going up hills isn't it.
