In a script:

/// <summary>
/// Attribute to select a single layer.
/// </summary>
public class SingleLayerAttribute : PropertyAttribute { }

In an Editor folder:

using UnityEngine;
using UnityEditor;

[CustomPropertyDrawer(typeof(SingleLayerAttribute))]
class LayerAttributeEditor : PropertyDrawer
{  
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
         property.intValue = EditorGUI.LayerField(position, label,  property.intValue);
    }

}

Usage:

[SerializeField, SingleLayer] private LayerMask myLayer;
// OR
[SingleLayer] public int mylayer;

Don't forget that in order to see a variable in the inspector, the field must be serialized (either set with [SerializeField] or set to public)
