You can't do this very easily, unfortuantely. The way PrefixQuery runs is to find (globally, across the index) all terms that have that prefix. If there are enough of them, it goes term by term marking the documents in a bitset, and then iterates that bitset in the end. So the information of which term matched which document is long gone.
If there are few enough terms, it makes a BooleanQuery with N SHOULD clauses, and in that limited case, since the child clauses are all visiting the same document when it's collected, you might be able to use the Scorer.getChildren API in a custom Collector to see (per doc collected) which terms are "on" that one document. You could alternatively store term vectors (but these are slow and costly) and load them for each document and iterate the matched prefix terms by creating a PrefixTermsEnum.
