g/\<INPUT\>/s/\(.*\)\(\<\w\+\>\)/\1(\2)/

or

g/\<INPUT\>/s/.*\zs\(\<\w\+\>\)/(\1)/

do this. The :global-command restricts the following substitution to
lines containing the word INPUT. The :substitute-commands first try to
match as many characters as possible in a line, but then they backtrack
to be able to match the right-most single word. The first command then
replaces everything that was matched with the part before the word and
the word itself in parentheses. The second command uses \zs to reset the
start of the match and replaces only the word with itself in parentheses.

Regards,
Jürgen
