Moto G, 1st or 2nd generation. Will get you everything you're looking for at a great price, and won't look or feel like a cheap phone.
I'd probably get the 2nd gen. Overall a lot of improvements, and you can pick them up without a contract for under $200.
edit: wait, are you looking to tether your phone to your tablet or your tablet to your phone? Certain models of the G don't have LTE/4G
