Found a solution for what I'm looking for:

declare @DBRoleName varchar(40) = '[dbrolename]'

SELECT 'GRANT ' + dbprm.permission_name + ' ON ' + OBJECT_SCHEMA_NAME(major_id) + '.' + OBJECT_NAME(major_id) + ' TO ' + dbrol.name + char(13) COLLATE Latin1_General_CI_AS

from sys.database_permissions dbprm

join sys.database_principals dbrol on

dbprm.grantee_principal_id = dbrol.principal_id

where dbrol.name = @DBRoleName
