If you don't have session where the PATH variable still has the old
value that you can look at and copy, then just restore the file that you
changed from a recent backup.
The closest to any "default value" for PATH that you will be able to
find is the output of
getconf PATH
This is however unlikely to be what your old PATH value was and it
may even give you a mostly unusable PATH value that does not contain
any binaries from 3rd-party packages etc. (and it will definitely not
contain any private paths).
