For your setup, I'd recommend either having a role to create an instance,
or a single playbook that creates an instance and later kicks off
ansible-pull. You really shouldn't have to be changing your use of the ec2
module across multiple files.
I would just choose values for the required variables so that they work in
either environment.
Let's say you have a group for VPC hosts (you might have multiple groups
for multiple VPCs) - and one for non VPC hosts
Then in the vpc1.yml, set things like vpc_subnet_id (looking at the docs
that's the only one you'll likely need)
In nonvpc.yml, have vpc_subnet_id: ""
And then when you use the ec2 module, pass
vpc_subnet_id: "{{vpc_subnet_id}}"
