You can use the returned data from cloudformation to call add_host
<http://docs.ansible.com/ansible/add_host_module.html>, then start a new
play that targets that host, or set up an EC2 dynamic inventory script that
will pick up the host(s) you're creating and conditionally call meta:
inventory_refresh when you know an instance got created (then do the same
thing: start another play that touches the right host(s)). I personally
prefer the add_host approach as it's more definitive that you're touching
exactly the right host, but potato, potahto...
