What do prisoners falsely accused (and exonerated) get in recompense?

In England and Wales there is something called the Odgen Tables which are used in Fatal accidents and Personal Injuries case to calculate how much the person would have earnt had the accident not occured. Its a graded system with allowances for a persons level of eductaion, age, prospects of promotion etc.

I think something similar would be used in prisoner companation cases.

There is authority for compensation for that. Here is a description of the system from the O’brien case, linked above:
