Spanish???
I know how to say what is your name in spanish. ¿Cómo te llamas? what would you say after you answered the question and want to ask them the same question back?

In your question, llamarse is conjugated in the tú form, so you would say ¿Y tú? However, if the question was ¿Cómo se llama? you would say ¿Y usted?
The difference is tú is informal (friend, juniors) while usted is formal (advisors, elders)
Hello Brin
Welcome to the SpanishDict forum 
You would say:
1.¿y Usted? in response to ¿Cómo se llama Usted? Polite form used when talking to an older person, a stranger or someone in authority like a teacher, a police officer, etc...
2.¿y tú? in response yo ¿Cómo te llamas? Familiar form used when talking to a child,/young person, a friend you know well or a member of your family.
Cultural note: The familiar tú form is used in Spain where they speak Castellano. In many parts of Latin America like Colombia people frequently address members if their family and friends using the Usted polite form.
¿Cómo se llama (Ud)? = What is your name? Usted is often shortened to Ud in the written form.
You can also say:
¿Cuál es su (tú) nombre? = What is your name?
However, some Spanish speaking natives have pointed out that this is a more formal way to ask this question and and is more commonly used in formal documents, or might be used by a police officer when questioning someone.
I hope this helps
¿Y tú? (informal)
¿Y usted? (formal - for older people etc)
or
¿Cúal es tu/su nombre.
Another way to ask is ¿y voz?
