The YAML file you have is a conda environment recipe, rather than a recipe for building a package (meta.yaml).

Conda channels (e.g. bioconda, conda-forge) have their own specific guides and methods for building packages hosted in those channels. It looks like you might be intending your package to be part of bioconda, their contribution guide is here: https://bioconda.github.io/contributor/index.html

In addition, you can browse examples of existing bioconda recipes in their GitHub repository: https://github.com/bioconda/bioconda-recipes. That can help you find a package that is similar to your own to see how they structured theirs.
