From PowerShell:

, 'y' * 2  | powershell -c 'read-host one; read-host two'

, 'y' * 2 constructs a 2-element array consisting of 'y' strings (the equivalent of 'y', 'y').

Used as pipeline input for an external program (which happens to be another PowerShell process in this case), PowerShell sends each element followed by a newline, which each answers one prompt in the PowerShell code.

From cmd.exe:

(echo y& echo y) | powershell -c "read-host one; read-host two"

Note: The use of (...) in a pipeline apparently invariably appends a space to each echo command's output, so that each prompt in PowerShell receives 'y <Enter>'; this shouldn't be a problem, but if it is, you can use an intermediate temporary file:
(echo y& echo y) >tmp.txt & type tmp.txt | powershell ... & del tmp.txt
