You can't unless you meet him/her again and add him/her. But it's very hard to add a deleted friend because it takes lots of friend requests and a lot of time to add them again. Sometimes it doesn't even work.
To add someone as a friend you have to meet them. Sensei is very hard to find (appearing on his seat in the Dojo does not count), there is even a stamp for achieving that. I am also not sure if Club Penguin allows to add a system penguin as a friend.
