Well I'd suspect that the mirror heater element will have got burnt out. To check this out you would need to measure the resistance of that heater - it should be quite low, if its rough 1K or more then you'll know its burnt out and is O/C - it is only the charred backing tape that is giving the high restistance reading.

As said above, its probably the heating element behind the mirror. You should be able to buy a new glass with heating element from seat for a few quid. To check this you could either check the resistance (as above) of the element, or check the voltage reaching the mirror (put a small 12V bulb across it momentarily if you dont have a volt/multi meter). The mirror glass shoould just pop out if you are carefull so you can check the above.
