well, one is playing scales slowly (at first) with as little LH pressure as possible, with your thumb barely touching the back of the guitar. same with slur studies, chromatic octaves, etc. the idea is to try and find the minimal pressure needed for any given LH exercise, and to carry this into your playing as much as possible. try to use the weight of your arm to press the notes as opposed to the strength of your thumb, which, as much as possible should serve as a guide or anchor. more generally the idea is to develop a mindful approach, so that you become conscious of all needless tension in the left hand. often when playing a chord in a piece, for instance, you won't need all LH fingers to be simultaneously pressing down. release tension whenever possible, in each finger; this might mean re-working pieces you already know, or re-arranging them for easier LH positions. also, in chords or positions requiring more force, you can sometimes take some pressure off the thumb by pulling the guitar towards your chest. there are lots of little tricks like this which have helped me, but I'm sure your teacher or other delcampers can help you with suggestions that might be better. I think the main thing is to try to become acutely conscious of all needless tension. it will take some time.
it might be worth adding that I found that guitar with unusually thin necks - around 19mm or under at the 1st fret - were not good. although this might be something peculiar to my individual hand anatomy, I have also heard it from one other person who had this condition. might be worth experimenting with a few other guitars if you have access to any.
