Transform new devices tracked automation to BP

Configuration
,
1

Ok, so @chemelli and I have conjured up this automation:

  - alias: New device registered config
    id: New device registered config
    mode: queued
    trigger:
      platform: event
      event_type: entity_registry_updated
      event_data:
        action: create
    condition: >
      {{trigger.event.data.entity_id.startswith('device_tracker')}}
    action:
      - variables:
          entity: >
            {{trigger.event.data.entity_id}}
          name: >
            {{state_attr(entity,'friendly_name')}}
          host: >
            {{state_attr(entity,'host_name')}}
          ip: >
            {{state_attr(entity,'ip')}}
          mac: >
            {{state_attr(entity,'mac')}}
          id: >
            {{device_id(entity)}}
          config: >
            entity:{{entity}},
            name:{{name}},
            host:{{host}},
            ip:{{ip}},
            mac:{{mac}},
            id:{{id}}
      - service: system_log.write
        data:
          message: >
            {{config}}
          level: warning
          logger: homeassistant.components.device_tracker
      - service: persistent_notification.create
        data:
          title: >
            New device registered: {{name}}
          message: >
            New device config: {{config}}

which works beautifully, and makes it very easy to check the new device and maybe edit it to suit your display needs in Lovelace.
We thought it would make a nice BP. However, since ive never used a BP before, and because of that have no real idea what we would need to change for it to become a BP, I am seeking some assistance from the community.

Which BP guru can help me out here? Any help is appreciated.

if remotely useful, for legacy device trackers one can still use:

  - alias: New device tracked legacy
    id: New device tracked legacy
    trigger:
      platform: event
      event_type: device_tracker_new_device
    action:
      service: persistent_notification.create
      data:
        title: >
          Newly tracked: {{trigger.event.data.entity_id}}
        message: >
          New device tracked: ({{trigger.event.data.entity_id}})
          Host: {{trigger.event.data.host_name}}
          Mac-address: {{trigger.event.data.mac}}
          Data: {{trigger.event.data}}

version 2 with additional options for notifications:

  - alias: New device registered config
    id: New device registered config
    mode: queued
    trigger:
      platform: event
      event_type: entity_registry_updated
      event_data:
        action: create
    condition: >
      {{trigger.event.data.entity_id.startswith('device_tracker')}}
    action:
      - variables:
          data: >
            {{trigger.event.data}}
          entity: >
            {{trigger.event.data.entity_id}}
          name: >
            {{state_attr(entity,'friendly_name')}}
          host: >
            {{state_attr(entity,'host_name')}}
          ip: >
            {{state_attr(entity,'ip')}}
          mac: >
            {{state_attr(entity,'mac')}}
          id: >
            {{device_id(entity)}}
          config: >
            - entity: {{entity}},
            - name: {{name}},
            - host: {{host}},
            - ip: {{ip}},
            - mac: {{mac}},
            - id: {{id}}
          message_body: >

             'message':'New device config: {{config}}'}
