If they're only 1-2 miles, then do hill repeats on those. Practice spinning, spinning, spinning until the quads burn. That will help your endurance. Then the next step is to spin up those longer climbs in larger gears. You might be able to get that next step in strength and endurance on the flats with tempo rides (a step below your time trial zone), long time-trial intervals, or hanging on for dear life in faster group rides with lots of surges. I include the latter, because that's the best way I've found to push myself far enough out of my comfort zone. Racing can also do it if you are in a fast group with a lot of surges. I have more success with the hammerhead group rides than my races (they aren't long enough really), and racing definitely isn't necessary. You just need to be able to add matches to your store and recover quickly.
One thing about the hill repeats on the longer climbs (and not the shorter ones) is that it forces you to look better at pacing yourself. Some people go way too hard at the bottom and then fizzle out. Start out with a slower pace, and you may still find you're spiking your heart rate, but that happens later, and it's just staying in that sustainable zone. Then, you're forcing your legs to keep up (hence the burn from spinning). You will start out slow, but if you work on increasing your overall strength and endurance with the longer intervals and shorter chasing intervals that nearly make you pop, then you'll be able to bring that back to the hills. So you'll have the same steady approach to the longer climb, but you'll be a cog or two harder than when you start.
From how you described your natural style now, it could take some time to build up. You may need to exaggerate spinning up (as easy of a gear as you can, at maybe 100-110rpms). That will help you build your muscular endurance. Then, enlist your natural strength and see what you can do with a harder gear and, say, 85-95 rpms. Then work on sustaining those cadences in an even harder gear (which may mean taking the 2nd gearing and going back to ultra-high cadences again).
Doing spinups is kind of how I spend a lot of the fall. Then when racing season rolls around and I work on my sprinting strength, I can apply that to hills by being able to hold a gear that requires more strength as well as I could spin a really light gear in the fall. You already have the strength part down, so take a step back and work on moving at pretty low speeds from the start of the climb but pretty high rpms to develop the slow twitch.
Does that make sense? Sorry, I feel like I was talking in circles.
