Converting Spraypaint typography smart object made in photoshop into illustrator

[MOETNCOMETH]

Hey guys, I am not as profiecient at all in adobe photoshop but after following a youtube tutorial on how to create spraypaint typography (For later use to print on a t-shirt) I was able to create just that. My biggest problem is being able to transfer this typography to illustrator so that it is vectorized and my manufacturer can print it. Any advice...? 8298
