It's a shortened form of the verb "ir" (to go) conjugated in the present tense with the pronoun "te" (you).
Here are some examples:
* Te voy a buscar. (I'm going to look for you.)
* Te voy a ayudar. (I'm going to help you.)
* Te voy a ver mañana. (I'm going to see you tomorrow.)
It's important to note that "te voy" is often used in a more informal context. In formal settings, you would typically use the full conjugation of "ir" with the appropriate pronoun.
