How to export existing configured and tested infrastructure (including AWS Lambda functions, API Gateways, ElastiCache clusters, Cloudwatch rules) to Cloudformation template?

I know about Cloudformer tool, but it supports limited number of AWS services (Amazon VPC, DynamoDB, etc) and don't supports some of services which we use. Which tools and approaches can I use in my case for generating Cloudformation template?
