The most important part for me is not the looking behind but the manoeuvre. Rather than signalling and pulling over start to drift slowly right a little way before the junction. When you get close to the centre of the lane, signal for five seconds and then complete the move. The gradual drift allows you to break naturally into a line of traffic in a way a signal and pull over won't.
Two other tips, if turning to look behind is difficult try looking down and under your arm. Second get a copy of Cyclecraft by John Franklin which gives invaluable advice about riding in traffic.
