Just grabbed this from reddit,
First I made some extracts of dry spices.
Ginger... 1 1/2 tablespoons dry powdered ginger.
Cinnamon... a stick, broken up into small pieces.
Allspice... lightly crushed, 2 tablespoons.
Cloves... whole, 1 1/2 tablespoons.
Nutmeg... 2 small nuts, lightly crushed.
Each of these was put into its own small (25ml) glass jar with 15ml PG. After that the jars were placed in a pot of simmering water on the stove for about 45 minutes. The PG in all the jars had acquired colour by then, so I let them cool and steep for a couple of weeks (I think I could have gone ahead right away, but I have been busy with other things).
The whole and lightly crushed spices are easy to deal with... just strain, let them settle and decant for an extract without any solid bits. The ginger settled into a thick paste on the bottom with a brown but clear fluid on top... I decanted the clear fluid.
I mixed the spice extracts up as vape juices on their own, all at 15% 60:40 PG:VG. They are all pretty convincing on their own... the ginger is hot, not too hot to vape. Cinnamon is hot too, and has a distinctly stick-cinnamon taste (you can taste a bit of woody fiber) that would taste good in an apple-cider juice. Cloves, nutmeg and allspice all taste good too.

It's a little more spicy than pumpkin pie should be, but very convincing. Perhaps the next batch I will try the spices at half the strength of this one.
Edit: Formatting
Edit: Update... add no more than 1% Lorann Pumpkin flavouring to give it an even more authentic pumpkin pie taste. Lorann Pumpkin is very, very strong stuff... any more than 1% causes an unpleasant bitterness, but at a very low level is quite convincingly pumpkin.
