In English if you mistake someone for another person it is common to say "I'm sorry, I thought you were someone else".
How should this be said in Chinese?

I think the most common way is:
我以为你是另外一个人
wo yiwei ni shi linwai yi ge ren
You could also say:
我以为你是别人
wo yiwei ni shi bie ren
Often you may say the name of the person that you think they are:
我以为你是 'someone's name'.
You may like to add:
不好意思
bu hao yisi
At the beginning of the sentence depending on the circumstance.
chentudou has great answer. I'd like to add
很抱歉,我看错人了
抱歉 for being extra polite
