A light hammer is a martial weapon, the OP asked for simple weapons...

As a simple ranged weapon, why not a +1 Returning Javelin?

Using a javelin was mentioned above. Please note that a javelin is a thrown weapon; you hurl it with your Strength. It also has a range of 30', which isn't much of a problem for a Monk to travel (also mentioned above). So it's usefull vs flyers, people on rooftops above you, etc.

I believe the Monk build mentioned above is Dex based rather than Str. Alas!

I am going to suggest a Monk with Tiger Stance (level 1), 1d8 S damage.

The Cobra Stance (level 4) inflicts poison; good enough for a Tooth attack?

The Tekko-Kagi could be used as claws.

The ideas shown above allow you to use any ancestry that strikes your fancy.

BTW - the Tengu gets a beak attack... good enough for tooth?
