Export virtual environment created with venv to yaml file [no conda]

Question

I have created a virtual environment using:
python3 -m venv env_name.
I worked with this and installed all packages required for my work using pip3. Now I want to export this to a remote server. Which takes only the YAML file, and creates a conda environment. So how can I export the YAML file for my environment (my_env).
Note: I don't have conda installed, so I need a solution without conda. Thanks for the help.
