I’m trying to migrate some paragraphs from D7 to D9.

The bundle type is always set by the default_bundle setting for the destination migration eg:

destination:
 plugin: 'entity_reference_revisions:paragraph'
 default_bundle: text

Can anyone sign post me to a good example of a yml file that sets this for paragraphs with more than one field?

Here is the whole yml file:

langcode: en
status: true
dependencies: { }
id: paragraph_text
class: null
field_plugin_method: null
cck_plugin_method: null
migration_tags:
 - 'Drupal 7'
migration_group: migrate_drupal_7
label: Text Paragraphs
source:
 plugin: d7_paragraph_item
 key: migrate
#  field_name is used in our custom plugin to get data about the paragraph item.
 field_name: field_paragraphs
process:
 temp_bundle_type:
  plugin: static_map
  source: target_bundle
  bypass: true  
  source: format  
  map:  
    - null
 type: '@temp_bundle_type'       
 field_text:
 - plugin: sub_process
   source: field_text
   process:
     value: value
     format:
       plugin: default_value
       default_value: basic_html
   revision_id: revision_id
 - plugin: debug
   label: 'Step 1: Value received from the sub_process plugin: '   
 field_quote_author:
 - plugin: sub_process
   source: field_quote_author
   process:
     value: value
   revision_id: revision_id
 - plugin: debug
   label: 'Step 2: Value received from the sub_process plugin: '      
destination:
 plugin: 'entity_reference_revisions:paragraph'
 #default_bundle: text
migration_dependencies:
 required: {  }
 optional: {  }
