*In place of the black tea, you can use a comparable amount of Thai Black Tea Mix (such as this one). However, these mixes typically contain yellow dye and I don't know how vegan-friendly they are. Based on my research, you can replicate the flavor by adding vanilla extract to black tea, as I've done above.
