Well first of all I would suggest that you look at some of the standard template answers such as Template::Toolkit rather than rolling your own.

But for your specific question, if %replace has your translation of key to value then you can do this: 

my $match = join "|", map {quotemeta($_)} keys %replace;
$str = s/<--($match)-->/$replace{$1}/g;
