Three suggestions, all about the same price, look for used models:
EF 28-70mm f/2.8L USM (discontinued, look ebay or KEH)
EF-S 17-55mm f/2.8 IS USM
EF 24-105mm f/4L IS USM
The low-light capabilities of your 70D coupled with IS will give an f/4 lens flexibility in many indoor situations with no flash.
Primes I'd look at the EF 50 f/1.8 and the EF 85 f/1.8
Shot the indoor part of a wedding with the 50 1.8. Very nice results. And let's not forget, pretty damn cheap.
