You could just call "y" at the beginning of the mapping:

vnoremap <silent> y y:call Hook()<cr>

This has the added advantage of making the yanked text available in the Hook function in case you need to do something with it.

You can do this because, first, you said "noremap" so the second "y" wouldn't trigger the mapping and would just do a yank and, secondly, Vim lets you start a mapped sequence with the keys that actually launched the mapping and falls back to their default behaviour automatically to avoid recursive mappings (so you could do this even if you hadn't specified a noremap).
