If you can get CTC leaves and some store-bought chai masala, you can a pretty good chai at home:
1 cup whole milk
1/4 cup water
1 tsp CTC tea leaves
1/2 to 1 tsp masala, to taste
1-2 tsp grated ginger
Bring it to a boil in a saucepan, and either lower your burner to medium, or move the pan so that it's only half on heating element, then boil it for 4 minutes and pour it through a strainer. Add about 2 tsp sugar or honey.
Many indians will use much less milk, and low-fat at that. And that's because they're pussies.
