Hi Jade,
If you mean "here you are" as to when you hand out something to someone, in informal French you coud say : Tiens! and formal French : Tenez! The verb TENIR.
You can also add : Le/las/les voici with the appropriate pronoun:
Example : Tiens, les voici. Tiens, le voici. Tiens, la voici.
J´espère que c´était utile,
