Y tu or y te?
Shouldn't y Tu, be y te, given that te is reflexive, yourself. Why is it y Tu?

It's because "tú" is the subject pronoun and "te" is the direct/indirect/reflexive pronoun.
In English they are all "you." In Spanish they are different. In the sentence, "And you?" "You" is a subject pronoun--subject of the unstated verb "are."
This is why you use the subject pronoun "tú" in Spanish.
There is no "reflexive" usage here.
It seems you need a clear explanation of what "reflexive verbs are." Here's a link to an article written by Moderator Ray76.

I think it is because it is a shorter way of saying (to use the example of "how are you") "¿Cómo estás (tú)?". The word "te" is not mentioned in that sentence - we do not say "¿Cómo te estás?" - therefore, the word "te" is also not used in the question "¿Y tú?". This is just a guess though!
