Answer

You can say....

先生、どうぞ。/先生、お注ぎします。（and then pour beer into a glass）
先生、いかがですか？
先生、（ビール）飲まれますか？

Answer

Hello, 
I guess you want to use these phrases for asking teachers " what kinds of drink do you want". Or  for when you will pour the beer to teachers.
At that time, you can use more simple phrases like "先生いかがですか？"  or "何か飲まれますか？".
There are other common phrases for nomikai. If you want to know more phrasee, ask me freely :-)
Thanks

Answer

注いでもいいですか
=ついでもいいですか
=tsuide mo ii desu ka (*not tsuiTe)
="may i pour your drink?"

往ってもいいですか
=いってもいいですか
=itte mo ii desu ka
="may i go?"

...and you cannot use masu form when you ask something in "may i ~" phrase. it must be いいですか？
