1)Over compensate when turning in low visibility situations and when I say over compensate I mean turn wider than you normally would when possible.
2)Slow down or stop till the traffic is clear so that you can safely over compensate.
3)Take the turns much slower if you need to in order to ensure that you don’t hit a curb or other obstruction.

It will come in time, however I still always check my mirrors turning. You never know if something that wasn't there (like a person) is suddenly there while you turn. I've had joggers go out into the street as I'm taking my turn and I have to stop and it takes them a second to realize that they need to get back onto the sidewalk so as not to get run over. At night, there is going to always be some risk. I like the others over compensate. I take as much room as I possibly can just to be certain that I'm not going to hit something that maybe I didn't see as I came to the intersection. Sometimes you can miss things like low hanging wires or maybe something laying in the road that could damage a tire.

There is no real secret to it, turning, and driving in general is more risky at night.
