Hello, can anyone aide me in deciding which smd MOSFETs to pick for this circuit?

Yeah... you want us to watch a 10+ minute video and construct a schematic ourselves?

Do YOUR homework and sketch a schematic of the circuit and post it here.

You need what are called logic level FETs. These are FETs with a low gate to source turn on voltage. If you go to a site like Mouser you can find them in the database. I would search for say a p channel with a threshold between 1 and 2 volts in a smd package and a current between 100 and 1000 ma.

edit: BJT might work better (cheaper).
