The buffer-local variable `default-directory' will help. It gives always
the default directory of a buffer, independent whether a file is visiting
this buffer or not.

If (file-remote-p default-directory) returns non-nil, the buffer is
related to Tramp. Even better, (file-remote-p default-directory 'method)
returns the connection method.
