A ForEach-Object is needed to iterate over the file names as well. Ternary expressions are in PowerShell Core, but I am not sure about Windows PowerShell. This is not tested, but might give a start.

Get-ChildItem -File -Path '.' -Filter '*.md' |
    ForEach-Object {
        $OutFile = ".\foo\$($_.Name)"
        Get-Content -Path $_.FullName |
            ForEach-Object { ($_ -match '^!') ? ($_ -replace '_','-') : ($_) } |
            Out-File -FilePath $OutFile
    }

Also, it is bad practice to use alias commands in a stored script.
