Hi Solal:
You can get some power-cli examples here to create VM here:
https://www.vmware.com/support/developer/PowerCLI/PowerCLI51/html/New-VM.html
You can look into the VCenter data acquisition script bundled with WFA for reference.
You can clone that in a command and modify.
Initially you can hard-code and not use any dictionary entries to make sure the command works to create the VM.
Later, you probably would need to create some dictionary entries to meet your workflow needs.
Let us know if you need any more help.
Some thread related to WFA here in case
