I've been looking around and haven't found it yet..

Where can I find a small temperature sensor on a long probe (like a
scope probe) to measure the temperature on 8pin SOIC chips and 1206
resistors?
The probe plugs in a DMM or similar readout.

Or do I get the E*bay rectal thermometer? :P
What a pita...

For thermocouples, there are some attached to flat pieces of steel. You migtht
want to customize one or make one.

For thermistors.
I have a probe in a small hypodermic needle, and I have a probe on a long
stainless steel bendable rod about .04 inch thick. Nether one would be good
for making contact. Your best bet is to do something like me. I ordered some
chip thermistors. I didn't buy it beacause it was flat, but that would
work in your case. Still need some grease to get some conduction.

Yup... I'm thinkn chip thermistor too.
It's the cheapest solution.
A blob of thermal epoxy is more expensive. :P

So I glue a bunch a thermistors on a few parts and it looks ugly. It's
just for a scruffy prototype.
I might try grease instead but seems messy.

I plan to connect small diameter wire to thermistors reduce heat
piping.
