What does してた in 元気してた means? How it came to being してた? I know that the
original form of し is する, then what does 元気する means? It's really confusing.

What does してた in 元気してた means?
> 「元気{げんき}してた？」

is just a more informal/colloquial way of saying:

> 「元気 **に** してた？」

which is already fairly informal. **You can only say these to close friends
and people younger than you**.

Both expressions mean:

> "Have you been alright?"

A more "textbook" way of saying this would be:

> 「（お）元気にされていましたか？」 or 「（お）元気でしたか？」

Those can be said to people older than you.
