If you're looking to continue to run, I've found counters to be effective in the goalline. The tackle will bypass the end and take out the lb...the fb/pulling guard will seal the end out. As long as the safety doesn't hit the hole before you it should be a td...if the safety his the hole try to truck your way in because there won't be much space.
If you are open to passing, try some corner routes, stick concept works well and generally has a backside slant as an option if they match up the stick. Spacing can be effective too. If your opponent plays man, mesh is an easy completion if you can get protection. Spot is hit or miss.
